Having problems with your 2002 Ford Escape ?
What are the three wires on the back of the alternator for and what color does what o2 ford escape
It depends on which system you have. In both cases, there is a black and yellow wire that goes to the fuse box and a 15 amp fuse. This wire provides stator current to run the alternator. There is also a yellow and white wire that goes to the fuse box that provides the charge current to the battery. Now depending on the system, there may be only one additional wire (light green/red) to the instrument panel battery light or there are 2 wires (brown/white and grey/orange) that go to the PCM. In the latter case, the PCM monitors the charge current and then turns on the instrument panel light when the charge current is insufficient. In the former case, the alternator has circuitry to determine when the batter light should turn on. OK? Is there a problem we can help you with?
